Check Digit Verification of cas no

The CAS Registry Mumber 130012-51-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,0,1 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 130012-51:
(8*1)+(7*3)+(6*0)+(5*0)+(4*1)+(3*2)+(2*5)+(1*1)=50
50 % 10 = 0
So 130012-51-0 is a valid CAS Registry Number.

A New Route to N-Monosubstituted Thioamides Utilizing Phosphoramidothionates as Reagents for the Thioamidation of Carboxylic Acids

DeBruin, Kenneth E.,Boros, Eric E.

, p. 6091 - 6098 (2007/10/02)

Several N-monosubstituted thioamides have been synthesized from the corresponding carboxylic acid chlorides and primary amines by a new procedure.The procedure utilizes a commercially available and inexpensive organophosphorus reagent (dimethyl chlorothiophosphate) to derivatize the amine, form the carboxamide bond, and accomplish the thionation of the carbonyl by an intramolecular rearrangement.The phosphoryl group is then cleaved from the resulting thiocarbonyl phosphoryl mixed imide by a simple hydrolysis.Thioamides (RCSNHR') containing a variety of functionality(R= simple alkyl, phenyl, bulky alkyl, cycloalkylalkyl, α,β-unsaturated, and alkyl with remote keto, ester, or amide carbonyl groups; R'= methyl, benzyl, allyl) have been prepared by this method in generally high overall yields (50-80 percent).Competing thionation of remote carbonyl groups or epimerization of a chiral center containing a proton α to a ketone group was not observed.
